Docker CI build fails due to missing 'Microsoft.Docker.Sdk'

[felschr]

Steps to reproduce the issue

(e.g. copy your Dockerfile or docker-compose.yml file here)

1. Create a ASP.NET Core 2.0 project with docker support in Visual Studio
2. Adjust docker-compose.ci.build.yml to use image microsoft/aspnetcore-build:2.0 if not already set
3. Run docker-compose -f .\docker-compose.ci.build.yml up

Expected behavior

Build succeeds

Actual behavior

Build fails with:
/src/docker-compose.dcproj : error MSB4236: The SDK 'Microsoft.Docker.Sdk' specified could not be found.

Additional information (e.g. issue happens only occasionally)

Happened to me after upgrading from ASP.NET Core 1.0 to 2.0.
I first noticed this issue when my build on VSTS failed.
Building from within Visual Studio 2017 works.

Microsoft.Docker.Sdk isn't included in the .NET Core SDK. It's only available from Visual Studio. See https://github.com/dotnet/cli/issues/6178.

Adjust docker-compose.ci.build.yml to use image microsoft/aspnetcore-build:2.0

What was the original image VS gave you? Changes are good they picked a different image, one that is designed to work with VS tooling.

@natemcmaster
I was using microsoft/aspnetcore-build:1.0-1.1 before without issues.

[natemcmaster]

Try this one: microsoft/aspnetcore-build:1.0-2.0. We had to custom make these "CI build" images to work with VS.

[felschr]

@natemcmaster
oh, awesome! I'll try it as soon as possible.
I didn't notice those builds. Is it documented somewhere where the differences between these images are?

[natemcmaster]

Is it documented somewhere where the differences between these images are?

None that I'm aware of. :-( VS + Docker tooling has some rough edges, and this is one of them.

[felschr]

Aaaaand it's working!!
Thanks a lot, @natemcmaster !

[natemcmaster]

Happy to help. Glad its working for you.

For anyone else hitting this issue, the solution is to use microsoft/aspnetcore-build:1.0-2.0.

Close in favor of dotnet/cli#6178.

@natemcmaster Is this image tightly coupled with VS? Still having the same issue when using microsoft/aspnetcore-build:1.0-2.0

Just tried, and I couldn't repro MSB4236 with microsoft/aspnetcore-build:1.0-2.0. If you're having trouble, please open a new issue with repro steps.

Heads up - we are deprecating microsoft/aspnetcore-build:1.0-2.0. See aspnet/Announcements#292
